AI agents call search_assay to retrieve information from OrigeneMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name suggests a search/query operation typical of biomedical information retrieval. The description is empty, which reduces confidence, but the naming pattern and the nature of sibling tools (all read-only data retrieval functions) strongly suggest this is a retrieval tool. No evidence of side effects, modifications, deletion, execution, or financial operations.
From the tool's definition Tool name 'search_assay' implies querying or retrieving assay-related data; no description provided to indicate write, destructive, or execution capabilities.
Documented attack patterns abuse exactly the kind of access search_assay gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OrigeneMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_assay:
{
"version": "1",
"default": "deny",
"tools": {
"search_assay": {}
}
}search_assay is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

search_assay. It is categorised as a Read tool in the OrigeneMCP MCP Server, which means it retrieves data without modifying state.
Register the Origene MCP server in PolicyLayer and add a rule for search_assay: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches OrigeneMCP. Nothing to install.
search_assay is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_assay rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for search_assay. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
search_assay is provided by the Origene MCP server (gentel-lab/origenemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OrigeneMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
